SERVICE OF PROCESS

(a) In a suit or action involving the enforcement of the conservation laws of this state or the orders of the commission affecting the conservation of the natural resources of this state, a Texas Ranger or an agent of the commission may serve civil or judicial process, citation, notice, warrant, subpoena, or writ, including process of every character in contempt proceedings, the same and as fully as a sheriff or constable of a county to whom the process, writ, notice, citation, subpoena, or warrant might be directed could within the limits of his own county. (b) A ranger or an agent of the commission may serve the process anywhere in the State of Texas although it may be directed to "any sheriff or constable" of a particular county. He shall make the same return as any other officer, sign his name, and add under his name the title of "State Ranger" or "Agent, Railroad Commission of Texas," as the case may be, which is sufficient to make it valid if the writ otherwise is properly prepared. (c) No fees are allowed the rangers or agents of the commission other than their regular salary or compensation.
